This publication summarizes the most recent advances in neurobiology, diagnostic approaches and therapeutics of the major dementing illnesses such as Alzheimer’s disease, frontotemporal dementia, Lewy body disease, and vascular dementia. In a succinct, practical and comprehensive manner, it provides an updated view of the disorders likely to be encountered in a daily practice. Each section is focused on a major form of dementia and is organized following the same scheme reviewing the pathophysiology of the disease, its diagnostic challenges, its characteristic neuroimaging features, therapeutic interventions and patient management issues. Avoiding an overspecialized approach, the book bridges the gap between clinical practice, advanced imaging, recent therapeutics and basic sciences. Thus, it serves as an excellent guide for mental health professionals working in the field of dementia as well as primary care physicians and students.
